Tumbas Point of Sale

A Laravel-based Point of Sale application built to production-ready stage for cashier and transaction management. I led a 3-person team covering design, backend, and frontend, then handled VPS deployment, server optimization, and automated backup.

Problem

Toko kelontong kesulitan memanage inventory, supplier, dan customer secara manual. Pencatatan laba-rugi, hutang, dan piutang sering tidak akurat yang menyebabkan kerugian finansial.

Solution

Membangun web-based POS berbasis Laravel untuk kebutuhan kasir dan manajemen transaksi, dengan perhatian pada alur operasional, pengelolaan data, deployment VPS, dan backup sistem.

Architecture Decisions

• Chose Laravel + MySQL for rapid development and team familiarity — reducing learning curve while maintaining reliability
• Implemented queue-based stock updates to handle concurrent transactions without race conditions
• Server-rendered pages instead of SPA for simpler deployment and better reliability on slow connections

Trade-offs

• Prioritized reliability over cutting-edge tech stack — the business needed stability, not innovation
• Accepted longer initial dashboard load for complete data accuracy
• Chose synchronous stock validation over optimistic updates to prevent overselling

Lessons Learned

• Error handling upfront saves hours of debugging in production
• Deployment and backup planning matter as much as feature work for business-critical cashier systems
• Always test with realistic data volumes, not just sample data

Features

• Product and stock management
• Daily sales with barcode scanning
• Multi-user access with roles
• Sales and debt reports
• Customer and supplier tracking
• Return & discount handling
• Multi-outlet and offline support

CV Highlights

Challenges Overcome

• Real-time stock updates during transactions
• Optimizing performance for large data
